I understand SQLite is perfectly capable of handling huge database files
without any issues.
Yet I'm convinced there may be some corner cases where there might be
legitimate reasons for wanting partitioning (like this
That said, I still didn't know the shell/CLI could do that. But 14.5 and
14.6 are pretty far down https://sqlite.org/cli.html so, I probably gave up

First off, I didn't know that SQLite could read from zip files directly. I
don't like it, but, I'm sure there's a use case somewhere.
Second, shouldn't SQLite only consider reading a file if the file size is
zero or if the appropriate SQLite header is found, and completely ignore

That is the likely explanation.

Thanks Dan. I just found another report regarding the hot journal,
"Hot-Journal with VFS",
https://www.mail-archive.com/sqlite-users@mailinglists.sqlite.org/msg112377.html.
It seems the same issue as I hit.
Thanks,

You can try some other sqlite wrapper for VBA, for instance vbRichClient ships
with 3.24 -- http://www.vbrichclient.com/#/en/Downloads.htm
Unfortunately as it's primary target is VB6 the stdcall port of sqlite is
compiled to x86 binary only.

Hi everybody,
regarding the geopoly module in version 3.25.2

shell was working corrrectly.

I find it strange that there's a big global lock problem with APFS considering
